摘要： A method and system for marking and verifying an information tag and a computer readable data storage medium having stored thereon computer code means for instructing a processor of a marking unit to execute a method of marking and verifying a received information tag are provided. The method for marking and verifying an information tag comprises generating a plurality of secret keys; transmitting one or more of the secret keys to one or more authorised marking units; and at each authorised marking unit, receiving the information tag; deriving a current access password based on a current mark associated with the information tag using one of the secret keys and verifying the current mark; setting the information tag into a rewriteable state using the derived current access password; generating a new mark and a new access password; and writing at least one of the new mark and the new access password into one or more rewriteable portions of the information tag.
